Description

[Detailed description of the invention] The present invention relates to an intermittent traveling processing device that cuts or processes a long workpiece at a fixed distance from a hole or notch formed in a long workpiece that is fed at a predetermined speed. be.

Conventionally, as shown in Fig. 1, a workpiece W is fed at a predetermined speed.
A hole H is formed in advance at a certain distance 11 from this hole H.
The traveling processing device, which is designed to cut at a distant position, mechanically or electrically detects the tip ■ of the workpiece and cuts a position 1□ away from this tip, thereby substantially cutting the workpiece at a distance of 1□. There are known devices that do this.

However, in the conventional system that detects the tip of the workpiece W, errors gradually accumulate and the dimension 1
1, errors occur in the process, making it impossible to obtain a regular product, and the device itself becomes complicated.

Therefore, the purpose of the present invention is to forcibly stop the pin that penetrates a hole or notch previously formed in the workpiece when it moves to a certain distance in synchronization with the workpiece, and based on this, the workpiece is also stopped in this stopped state. In order to eliminate the above-mentioned drawbacks, the press device is activated to perform the processing, and will be described in detail below using examples.

FIG. 2 is a plan view showing an embodiment of the intermittent traveling processing device according to the present invention, and FIGS. 3 and 4 are sectional views of the processing device shown in FIG. 2, and in each figure, 1 is a flat slide. A pin boulder 3 that guides the pin 2 in the vertical direction is placed on the top of the slide base 1, which is a base, and the pin boulder 3 is guided so as to move along the moving direction of the work 4.

As shown in FIG. 5, a part of the workpiece 4 has a hole 41 or a notch formed therein, and the workpiece 4 has a guide space 7 formed at the lower side of the guide panel 6 by the pinch roller 5.
is guided in the direction of arrow a.

The holder 3 has a spring 8 that always presses the pin 2 toward one side of the workpiece 4, and this spring 8 causes the pin 2 to penetrate into the hole 41 when the pin 2 corresponds to the hole 41 of the workpiece 4.

With this penetration, the holder 3 is moved to the base 1 in synchronization with the workpiece 4.
A stopper 9 slides on the top and is placed at a predetermined distance apart.
The workpiece 4 is stopped at this position when it hits the workpiece 4.

At this time, the pinch roller is in a slip state.

The holder 3 has a spring 1 in the opposite direction to the traveling direction of the workpiece 4.
It is driven by 0.

The holder 3 pulled by this spring 10 is moved to the stopper 1
It is stopped by 1.

The holder 3 is provided with a shaft 12, and a dock 13 is slidably disposed on the shaft 12. The dock 13 is constantly pressed in the direction of the holder 3 by a spring 14, and as the holder 3 moves, the dock 13 is slidably disposed on the shaft 12. The dock 13 is moved in synchronism and a switch 15 placed on the movement trajectory of the dock 13 is actuated, and the press device 16 is actuated by this switch 15.

Note that in conjunction with the operation of this press device 16, the punch holder 18 that holds the punch 17 operates, so that the punch 1
The tip of the pin 7 presses the head of the pin 2, which has penetrated into the hole 41 formed in the workpiece 4, downward.

According to the above configuration, the pin 2 is always pressed against the work 4 by the force of the spring 8 while the work 4 is guided by the pinch roller 5 and travels, and when the pin 2 corresponds to the hole 41 of the work 4, 2 penetrates this hole 41, so the holder 3 moves together with the work 4, and when it slides on the base 1 to a certain distance, the holder 3 comes into contact with the stopper 9 and stops at this position, so this Therefore, the workpiece 4 is also forcibly stopped.

Further, at the same time as or just before the holder 3 contacts the stopper 9, the dock 13, which has moved in synchronization with the holder 3, activates the switch 15, which activates the press device 16. This means that parts at distant locations will be processed.

Further, during this machining, the punch holder 18 moves downward, so the punch 17 presses the head of the pin 2 downward, and as a result, the pin 2 is pulled out of the hole 41 and is no longer secured to the workpiece 4, and the holder 3 is attached to the spring 10. It moves to its original position due to the traction force, contacts the stopper 11, and stops at this position.

As a result, the workpiece 4 is moved again by the pinch roller 5, and by repeating this operation, a position in the workpiece 4 that is a predetermined distance away from the hole 41 can be machined.

That is, according to this embodiment, a hole or notch pin formed in a workpiece running at a predetermined speed is inserted, and a pin holder is moved in synchronization with the workpiece through this pin, and after the pin holder has moved a predetermined distance, it is moved by a stopper. The above-mentioned holder is stopped, and the press device is activated at or just before this stop to perform processing, which ensures reliable processing and enables the formation of high-quality products. Since this is done as a standard, no cumulative errors occur, and the structure is simple, which is advantageous in terms of maintenance management.Furthermore, it is possible to process workpieces that are guided at high speeds, increasing processing speed and mass production. It becomes possible to aim for.

Although the present invention has been described as operating the press device 16 based on the operation of the switch 15, the cutting device may be operated in response to a signal from the switch 15 to perform the cutting operation.
